The Democratic Advocate, August 23, 1918
Charles Winter Jones, Ridgeville, among the drafted soldiers leaving for Camp Meade.
The photo is sometime after 1915 (Watkins). Jones is the garage “Manager” in 1919 and “proprietor” in 1920.
I wondered if the photo is of a young man proud of his new business and was taken in 1919-1920.
But now with the discussion on pumps, maybe it’s a photo celebrating the installation of new gas pumps in the 1920s.
